Intermittent haze when heating - microscopic bubbles?

[YoPool]

Just started getting haziness when heating my pool. Much more apparent in the spa due, I think, to the fact that its a more concentrated space then the pool. If I shut the pump off the haze dissipates in a couple of minutes. I have checked the chemistry (PH - 7.6, Calcium Hardness -310, Total Alkalinity - 70, and Chlorine -6 ppm) and everything is good. Its also intermittent - meaning that if I let the pool continue heating with the pump on the haziness will go away on its own some times. Almost like the system is "randomly" is introducing microscope bubbles into the water system. When i look closely I can see the bubbles (almost like really concentrated, extremely small champagne bubbles). I haven't done enough testing to be certain but it appears that just running the pump without the heater on does not cause it. Just wondering if anyone else has experienced something like this and any insight to what is happening. Thanks!

That type of thing is usually related to the SWG. Try turning the SWG off to see if that makes a difference.

Thanks! I will try that

The haze definitely appears to happening when the SWG is on as you thought JamesW. It also looks like the heater being on when the SWG is active may be part of the cause as well.

So the question now is this anything to br concerned about or is it normal?

Have you used any type of algaecide?

Certain chemicals will cause a reaction in the SWG.

I have not. Just the normal chemicals to keep the CH and PH in check. I add 4-6 ounces of muriatic acid every 2-3 days

This happens sometimes, but I don't know why.
